Abstract
The invention discloses a down-hole tool pressure testing device. The down-hole tool pressure testing device is mainly composed of a water storage device (1), a plurality of pressure testing pipes (2) and pressure testing pumps (3), wherein the pressure testing pipes (2) are connected with the water storage device (1), the pressure testing pumps (3) are all communicated with the pressure testing pipes (2). The down-hole tool pressure testing device is not only capable of carry out seal performance tests of down-hole tools with different models, but also capable of carrying out strength tests. Technology standard requests are completely achieved. Occurring of quality accidents that tools lose or taking off and falling off are caused by steel components deformation and the like is avoided.
Description
Technical field
The present invention relates to a kind of downhole tool pressure testing device.
Background technology
At home and abroad in crude oil production, mechanical oil recovery has occupied space of top prominence, and in mechanical oil recovery take oil well pump as main.Oil well pump is the most basic, the most reliable a kind of, scope of application pumping tool the most widely.According to statistics, shared ratio is more than 90% in mechanical oil well for oil well pump, and oil well pump equipment plays vital effect to whole crude oil production, due to oil rig particularly the economic loss that causes of the fault of downhole hardware be extremely huge.Therefore, in time and the working condition of monitor and judgement oil well pump, and the fault that occurs is processed effectively and timely, not only can greatly be reduced the cost of production of crude oil, obtain higher economic benefit, and will help further to improve the level of scientific management in oil field.
The most manual work that rely on of traditional oil pumping well detection and diagnosis mode are completed, and namely by patrolling the mode of well, then the manual critical data that gathers oil well work is passed through to calculate, or rule of thumb judged the working condition of oil well.This mode obviously can't satisfy the active demand of oil field development.Current, the collection of well data, detection and diagnosis have become the major reform target that realizes that digitlization oil field " cost efficiency " raises the management level, by setting up the field produces monitoring diagnosis system, realize the real-time analysis transmission of pumpingh well data and the seamless link of information network, progressively form the information network of producing control integration, become the ideal solution of oilfield well network monitoring and Production scheduling management.
Downhole tool is that oilfield enterprise has bored workover treatment and carries out smoothly one of important guarantee.The downhole tool management of field produces enterprise has its uniqueness: the production operation circumstance complication is changeable, and the behavior in service of downhole tool also is among continuous variation, and effective enforcement of having bored workover treatment depends on downhole tool and is in good working order; The downhole tool kind is many, it is wide to distribute, and a large amount of mobile downhole tools is wherein arranged, the containing much information of management; The downhole tool value ratio is more expensive, help enterprise to carry out detection and the reparation of downhole tool, change the present situation that in the past only detected by artificial experience, strengthen to greatest extent downhole tool in the information system management of field produces enterprises, improve the downhole tool service efficiency, can bring direct economic benefit for enterprise.
Downhole tool is the down-hole process pipe string important component part of oil field layered production practice, is divided three classes by function: packer class, control tool class, workover tool class.Seperated layer water injection is exactly in a bite water injection well, utilize packer that multiple zone is divided into some intervals, when adding persistent erection, low-permeability oil-bearing stratum flooding, by adjusting the restriction loss of downhole choke, the high permeability oil reservoir is controlled water filling, enable keeping under the relatively stable water injection pressure of well head, high, medium and low permeability oil reservoir is a technological measure of energy water filling all.
Oil well pump, downhole tool (packer and injection well downhole flow regulator) are the nucleus equipments of oil recovery, water filling, and its quality good or not is most important for the normal production of oil-water well.Especially be oil recovery factory's service as one, undertake that oil well pump, downhole tool detect, the grass-roots unit of repair, improve constantly repair rate, strengthen quality control and guarantee its outgoing qualified be the most important thing of work in every.
The downhole tool pressure test process is mainly used in all kinds of downhole tool experiments of sealing performance.This flow process came into operation in nineteen ninety, pressure source is SYB-350 pressure testing unit, and its safety test pressure is 25MPa, during upgrade, transform, hydraulic test pump and connecting line be serious aging, and many places are oozed, are leaked, and the instrument pressure testing of causing can only reach 20MPa, can't satisfy the leakage test requirement of the minimum 25MPa of downhole tool such as packer, injection well downhole flow regulator, and, because flow process is aging, spinosity possibility of leaking all at any time, operating personnel's personal safety is arrived in serious threat.In recent years, progress along with technology, technical indicator and work quality to lower well tool are had higher requirement, and only the test pressure of 20MPa can't satisfy the needs (requiring to reach 35MPa as Y341 type packer experimental pressure) that newly advance and repair rear downhole tool quality inspection.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of downhole tool pressure testing device is provided, this pressure testing device not only can carry out the experiments of sealing performance of each model downhole tool, also can make a strength test, reach the technical standard requirement fully, avoided instrument leakage or the distortion of invar spare and the generation of the quality accidents such as taking off of breaking.
Purpose of the present invention is achieved through the following technical solutions: the downhole tool pressure testing device, some pressure testing pipes that mainly are connected with water storage device by water storage device and the hydraulic test pump that is connected with pressure testing Guan Jun consist of.
Described water storage device is water tank.
Between described water storage device and pressure testing pipe, the water storage valve is installed.
Between described hydraulic test pump and pressure testing pipe, the pressure testing valve is installed.
In sum, the invention has the beneficial effects as follows: not only can carry out the experiments of sealing performance of each model downhole tool, also can make a strength test, reach the technical standard requirement fully, avoid instrument leakage or the distortion of invar spare and the generation of the quality accidents such as taking off of breaking.
